   • Extended ASCII

3. Image

   • Bitmap
     • Pixels
       • DPI/Resolution
       • Pixelates the more you zoom in
   • Vector
     • Infinitely Scalable
     • SVG
       • Lossless
     • Uses mathematical formulas to draw lines and curves that can be combined to create an image from geometric objects such as circles and polygons.

4. Sound

   • Analogue to Digital conversion
   • Digital to Analogue conversion

5. Compression

   • Lossless
     • Smaller Size Reduction than Lossy but no important data is loss
   • Lossy
     • Larger Size Reduction than Lossless but, in turn, Potentially important information is lost
